量子万花筒与贝尔定理

Quantum Kaleidoscopes and Bell's theorem

P. K. Aravind

摘要:

量子万花筒被定义为一组观测量或状态,由许多不同的子集组成,这些子集提供了贝尔-科亨-斯派克(BKS)和贝尔非定域性定理的密切相关的证明。万花筒通过一个简单的奇偶性论证证明了BKS定理,如果使用正确的纠缠,它也可以作为贝尔非定域性定理的证明。本文介绍并讨论了三种密切相关的万花筒:15态万花筒、24态万花筒和60态万花筒。这些万花筒的密切关系,以12点和16线的配置被称为雷伊的配置指出。“旋转”需要使每个万花筒产生所有的幻影被奠定了。这个60态万花筒,其基本几何结构是10个相互连接的雷氏构型(连同它们的几何构型),共有1120个幻影,为两个贝尔定理提供了证明。讨论了这些万花筒在量子层析成像和量子态估计中的一些应用。

英文摘要:

A quantum kaleidoscope is defined as a set of observables, or states, consisting of many different subsets that provide closely related proofs of the Bell-Kochen-Specker (BKS) and Bell nonlocality theorems. The kaleidoscopes prove the BKS theorem through a simple parity argument, which also doubles as a proof of Bell's nonlocality theorem if use is made of the right sort of entanglement. Three closely related kaleidoscopes are introduced and discussed in this paper: a 15-observable kaleidoscope, a 24-state kaleidoscope and a 60-state kaleidoscope. The close relationship of these kaleidoscopes to a configuration of 12 points and 16 lines known as Reye's configuration is pointed out. The "rotations" needed to make each kaleidoscope yield all its apparitions are laid out. The 60-state kaleidoscope, whose underlying geometrical structure is that of ten interlinked Reye's configurations (together with their duals), possesses a total of 1120 apparitions that provide proofs of the two Bell theorems. Some applications of these kaleidoscopes to problems in quantum tomography and quantum state estimation are discussed.
